Kassian Cephas or Kassian Céphas (15 January 1845 – 16 November 1912) was a Javanese photographer of the court of the Yogyakarta Sultanate. He was the first indigenous person from Indonesia to become a professional photographer and was trained at the request of Sultan Hamengkubuwana VI (r. 1855–1877). After becoming a court photographer in as early 1871, he began working on portrait photography for members of the royal family, as well as documentary work for the Dutch Archaeological Union (). Cephas was recognized for his contributions to preserving Java's cultural heritage through membership in the Royal Netherlands Institute of Southeast Asian and Caribbean Studies and an honorary gold medal of the Order of Orange-Nassau. Cephas and his wife Dina Rakijah raised four children. Their eldest son Sem Cephas continued the family's photography business until his own death in 1918. Early life Kassian Cephas was born in Yogyakarta to the Javanese couple of Kartodrono and Minah. As a youth, Cephas became a pupil of Protestant Christian missionary Christina Petronella Philips-Steven and followed her to nearby Bagelen, Purworejo. He was baptized there on 27 December 1860 at the age of fifteen and took the name of Cephas, the Aramaic equivalent of Saint Peter's name, as his baptismal name. He began using Cephas as a family name following the baptism. Photography career Upon Cephas' return to Yogyakarta in the early 1860s, he began training under Simon Willem Camerik, a member of the civil militia and court photographer of the Yogyakarta Sultanate. Cephas' training was conducted at the request of Sultan Hamengkubuwana VI, who noted his talent for photography. He became the appointed court painter and photographer as early as 1871. Cephas' studio was located on the second floor of the building where he and his wife lived in Yogyakarta's Lodji Ketjil Wetan area, now known as Major Suryotomo Street. His photography business was not the only one established in the area during this time period. Aside from portrait photography, Cephas also produced many works on buildings and ancient monuments. This included photographs of the Taman Sari Water Castle (1884) for the Royal Batavian Society of Arts and Sciences. Professional works His work first appeared for a wider public in 1888 in the publication In den Kedaton te Jogjåkartå by Isaäc Groneman. The book included 16 collotype prints of the art of Hindu Javanese dances. Groneman wished to generate interest in this culture in
